On Sunday, February 3, 2013, astrophysicist Neil deGrasse Tyson, who is the Frederick P. Rose Director of the Hayden Planetarium, reached a Twitter milestone: a million followers for his tweets from @neiltyson.

The new Action Comics #14, published this month by DC Comics, reveals that even Superman visits the Museum’s Hayden Planetarium—and not just to see the Space Show. The superhero, it turns out, comes once a year to see images of his far-off home planet, Krypton, said to orbit its home-star every 382 days. To locate the fictional planet in the actual sky, DC Comics worked with astrophysicist Neil deGrasse Tyson, director of the Museum’s Hayden Planetarium. Watch a video about the process.
